Hello,
need help with the following problem.

Why is É (201) between A (65) and Z (90)?

Local l as Logic
Local c as string
Local n as dword

n := Asc("É") <--201
n := Asc("A") <-- 65
n := Asc("Z") <-- 90

c := "É"
l := c >= "A" .and. c <= "Z" <-- is true

thank you
Thomas

Hi Thomas,
that depends on your nation module (if you are using a nation module) or your system.
The German nation module and/or a German language system should sort that between "E" and "F".

Hi Wolfgang,
thanks for the explanation.
I only want to allow the letters "A" to "Z". Do I have to check the Asc() values. Is that enough?
Or better look for a .Net-Method?
Thomas

Hi Thomas,
if you are using the VO runtime, you can use the ASC() function.
The Char:IsLetter() method returns true for every valild unicode character.
On your string you could use regular expressions: Source: https://stackoverflow.com/questions/128 ... rom-a-to-z
